ᐅ Installation situation of a walk-in shower with floor-level entry

Enigma8Hello everyone,
We would like to install a walk-in shower with a floor-level drain. However, I am wondering if the installation situation allows for this:
At the edge of the shower area, there is a DN100 (4-inch) waste pipe installed, to which the shower drain would need to be connected. In the same room, there is only a toilet connected.
Since the DN100 waste pipe already protrudes above the floor level, I am questioning whether this setup would work or be allowed.
If the DN100 pipe were completely filled with water, the shower water would flow out...
But in practice, this is probably never the case, right? How high does the water rise when the toilet is flushed?
Would this work?
I hope the attached image clarifies the installation situation!

Is this about a new build and planning, or the current condition and retrofitting of the walk-in shower?It concerns the current condition!Honestly, I don’t fully understand the drawing, but basically, wastewater pipes are never completely filled with water (unless they are clogged); they always contain some air as well (which is why they need to be vented depending on their length). The level of fullness is referred to as the fill ratio – this should be at least 0.5 (i.e., pipe half full) and usually should not exceed 0.7.
Branches, however, may only be connected at a horizontal angle of 45° and with a slope of 15° downward into the continuous (horizontal) pipe – which will probably be quite difficult or even impossible in your case. According to your drawing, you don’t even have enough height difference to create a proper slope between the trap and the pipe.
Can you break up the floor to lay the DN100 pipe deeper?

I’m just wondering how it looks if the 100 millimeter (4 inches) pipe is positioned higher than the floor. Will you be able to achieve enough slope by then?
I’m still having a bit of trouble visualizing it. Could you please upload a photo?
